4. Bo Derek

Anyone who thinks of Bo Derek thinks of 10, her 1979 film that drove men wild. Fortunately for her fans, they didn’t have to wait long to see her in Playboy. Derek posed in the magazine for the first time a year later, and her 12-page pictorial is one of the most celebrated in the magazine’s history. She appeared in Playboy twice in 1980, and followed those pictorials up with a number of regular appearances in the next five years, making her one of the hottest models in the early 1980s.
